When he got a job that required he work Sundays, he couldn’t go to church on Sundays.

There was a service at his church early on a Wednesday morning. Cooper went to that, instead of attending on Sunday. He did that for three years.

The minister told him that Sunday was the Sabbath, and he was breaking one of the Ten Commandments by not keeping Sunday holy. Going to church on Wednesday didn’t make Sunday holy. It wasn’t good enough.
